Question

Radioactive dating involves determining which of the following?

Half-life decay

Index fossils

Depth of layers

Geologic time

Answer 1

I’m pretty sure the answer is half life decay, we did an experiment in my science class on it last year.

Answer 2

Half-life decay

Step-by-step explanation:

Radiometric dating or radioactive dating, as it is also known, is a very useful procedure to determine the age of different ancient elements like minerals and rocks, comparing the present amount of a certain isotope which is radioactive in the material with its decay products, through the use of established decay standards.
